(ci. '3s-22) Claims.

This invention relates to insoles and particularly to insoles for use in the manufacture of welted shoes.

Insoles for welt work are usually prepared b the making of an insidechannel and an outside channel and turning the channel iiaps up against each other to form a sewing rib. Sometimes an outside channel flap alone is used to form the sewing rib. In order to provide in this manner a rib of adequate strength it is necessaryto employ leather of good quality and frequently even the better grades of insoles are reinforced with a layer of canvas covering the body of the insole and extending up the inside of the rib to the top thereof.

Objects of this invention are to provide an insole having a rib of great flexibility and adequate strength which will be firmly anchored to the body of the insole and in which the channeling and reinforcing operations are omitted or reduced to a minimum.

The illustrated insoles, which embody my invention, are each provided with a series of vloops of strong thread positioned and arranged to reinforce a sewing rib. The insole may be channeled to provide either an inside or an outside channel flap and the series of loops ,formed through the body of the insole adjacent to the channel flap, the loops being preferably secured (for example, by cement) to the channel ap to form a strong sewing rib firmly anchored t the body of the insole.

In another form of the invention, the insole is channeled to provide both an inside and an outside channel flap and the series of thread loops is anchored in thebetween-substance along a line between the channel flaps which are preferably cemented to the series of thread loops, a very strong connection between the sewing rib and the body of the insole being thus established. For some purposes an unchanneled insole may be provided, along the line where the usual sewing rib is located, with a series of thread loops formed by passing loops of thread through the body of the insole, the thread loops being preferably reinforced, at least on the inner side, with a strip of canvas one marginal portion of which is secured to the body of the insole and the other marginal portion secured against the inner face of the series of thread loops. This construction avoids any channeling operation and the strip of canvas provides a continuous surface on the inside of the sewing rib so that no obstruction is offered to the passage ofthe channel guide of the inseam sewing V'machine along the inner face of the rib.

Fig. 2 is a fragmentary View in perspective and in section illustrating a form of insole having an outside channel flap on one side and. a similar flap on the other side, loops of thread being anchored in the body of the insole between the flaps to reinforce the outer side of theoutside flap and having their anchorage to the body of the insole concealed by the other fiap;

Fig. 6 is a fragmentary sectional view of a welted shoe made by utilizing an insole of the type illustrated in Fig. 5.

. In Fig. l of the drawing, the numeral l0 indicates an insole having an inside channel l2 the lip I4 of which is turned up. Along the base of the lip I4 on its outer side a series of thread loops I6 is formed. by passing loops of a continuous thread through the insole from its inner side to its outer side, the loops lyingin close proximity to the outer face of the inner .lip lli.

f The series of thread loops may be formed by hand, by the use of a fairstitch machine such as that disclosed in Letters Patent of the United States No. 563,871, granted July 14,- 1896, on application of Edward F. Mower, or by the use of a lockstitch machine such as fthatrclisclosed in YLettersPatent of the United States No. 473,870,

'of the loops I6 is discontinuous.

tension on one of the threads, that is, the thread IS, will be loosened and that on the other thread, such as I8, tightened so that the series of loops will be formed in the thread I3, and the thread I8 will merely pass directly from loop to loop.

VBy pulling on the ends of the thread I8 the body has been split in from its edge to form three flaps or portions 22, 24, 26, the loops of the thread I6 being inserted through the portion 24 and the anchorage of the thread loops covered by the Vflap 2E. Thus an insole having a rib is provided the inner face of the rib of which is perfectly smooth and the outer face ofwhich has a discontinuous reinforcement.

In Fig. 3 an insole body 3U is provided with an outside channel the flap 32 of which is upturned. Then, through the feather portion 34 of the insole, loops of thread I6 are inserted, a series of loops'lying just outside the erect flap 32. lThus the insole is provided with a lip one part 32 of which is continuous and the other part composed To provide a smooth surface on the inner face Aof the insole a covering layer 38 of suitable material may be applied to that face and preferably is carried around the edges of the feather portion 34, as

ginal portion of which is secured to the body` of the insole 40 and the other marginal portionY of which is laid against the inner face of the series of loops and preferably secured thereto, for example -by cement. If desired, of course, a cover like that shown at 38 in Fig. 3 may be used.

If desired, a ythread like that shownat I8 in' Fig. l may pass through the loops I6.

Still another construction in which an insole rib is provided part of which is continuous 'and part discontinuous is illustrated in -Fig. 5. In this case an insole body is provided with an outside channel flap 52 and an inside channel flap 54,

as is usual inthe manufacture of welt insoles.

Then, to reinforce and strengthen the rib formed by the flaps52, 54, a line'of loops I6 similar to those shown in Fig. 3 is inserted through the" between-substance of the insole so that the series of loops lies between the two flaps, and the loops and the flaps may be secured to-each other by cement. yIn this construction the composite ribis rrnly anchored to the insole by the thread which Vpasses from loop to loop on` the inner side of the insole.V In case this thread, which has` the appearance of stitches on the inside of the insole, is objectionable, a cover like thatshown at,38 in Fig. 3 may be provided.

`In use, any of ,theabove-described insoles will berattached to a last 60 (Fig. 6) and upper lmaterial`s-62 will belasted over thev marginalportion or' feather or theinsole against the outside of the rib., The appetit? 'and .www @will than 'be ttached by stitches 63 to the rib, the stitches passing through the continuous portion of the rib and embracing one or more of the strands of thread forming the loops I6 which constitute a discontinuous reinforcement for the lip. It will be apparent that the thread loops, either alone or in connection with a continuous member formed integral with the insole or attached thereto, will afford a very strong and dependable anchorage for the stitches 66 even when, as is usual, the top portion of the rib, including the bights of the loops and the strand of thread I8, if present, are trimmed oli flush with the sole-,engaging iace of the welt 64. In completing the shoe, a filler 63 will be -applied to the shoe bottom, and a sole T0 laid thereon and attached to the welt 64, forexanple, by stitches l2.
